摘　　要： 对40个杧果品种(系)的花瓣和花药颜色进行数字化描述,即采用Photoshop CS3软件对试材图像进行处理,分别提取花瓣和花药颜色典型色域的CMYK模式参数,通过C、M、Y、K的百分比值确定其颜色。结果表明,用C、M、Y、K的百分比值能较准确科学地表现杧果花瓣和花药的色彩,可以反映品种(系)间差异。通过UPGMA聚类分析,将花瓣和花药颜色分别分成7个类群和4个类群。本研究为种质色彩描述与新品种选育指标提供新的数字化方法。 The colors of petal and anther collected from d0 mango cultivars were digitally described and deter- mined by using Photoshop CS3 to extract the parameters of CMYK pattern in the typical color region. Results showed that the percentage of C,M,Y, and K could more accurately and scientifically represent the colors of petal and an- ther and reflect differences among varieties of mango. They were divided into seven and four groups by UPGMA cluster analysis. The research will provide a new digital and scientifical method for germplasm description and new cultivar breeding of mango.
